We've got to solve the true problem, not patch around it. If the
OpenJDK on some of the distros is defective or untested, we are not
going to solve that problem by providing a binary download that hasn't
been tested on that distro. That just takes us back to the dreadful
state of affairs before all the distros packaged OpenJDK.

That's a reasonable operational definition of "important".

All of these are easily downloadable on all the distros. That's what
distros do very well. I remember the bad old days of free software
where you really did have to grab a compiler from here, developer
tools from there, and so on. It was horrible.

Fair point. That is a valid technical reason for keeping a bunch of
old Java binaries around. It would be a valuable resource for
developers. It would be a Bad Thing, to say the least, if end users
ended up using these downloads.

Fair enough. But encouraging people do use binaries that have been
put on a site that may or may not have been tested and may or may not
have any kind of update mechanism is *dangerous*. I can't stress

Of course it is! But you don't get a binary by just building it, or
at least a binary that a reasonable person would trust.

You're saying it as though OpenJDK not providing binaries is a bad
thing. It's not. OpenJDK is, and has always been, a source
distribution, for the reasons that I have tried -- apparently
unsuccessfully -- to explain.
It would be fantastic if someone could put in place a mechanism to
build and update properly tested OpenJDK binaries for all operating
systems. But it is not just a matter of doing a build and putting it
on a web site somewhere: with distribution comes responsibility.
I admit that this is a free-software-centered viewpoint. I apologize,
but that's the only viewpoint I have.
